... I read it and except of BS like "sanctions being helpful", "the leader being 26 years old lady" etc., it is quite interesting; I'll very briefly summarize what I recall (I'm no expert, so if you don't like it, don't read it, but don't tell me OK):
  • they use glass, not plastic (the disadvantages are obviously fragility and weight; obvious advantage is transparency, the other include heat resistance and the possibility to apply coating(s))
  • they worked around disadvantages, claim they have exceptionally tough glass which is lighter than plastic would be
  • they utilize the advantages in what they then call construction optics material (OK that's how I translated it :)
  • stuff I described above is used for PAKFA canopies (including folding sections), which of course is complicated due to the shape etc.: several glass sheets are first like baked to collapse into one durable, hardened part (the picture taken before this process is in your post https://www.sinodefenceforum.com/pak-fa-fgfa-discussions.t7155/page-141#post-397402) which is then cut by lasers and coated

13 orders from 2020. Su57 progress is slow compared to USAF 5th gens. By the time the ruaf gets to train properly in it, the USAF will be ready to test 6th gen concepts.

The Su-47 was a prototype which competed against the MiG 1.44 prototype in the Soviet equivalent of the ATF competition. They flew it around a bit to see if it would attract investment. It never did. It also had issues with airframe fatigue (as do nearly invariably all forward swept wing designs) which kept it out of consideration as a main program. While the MiG 1.44 was obsolete by the time the RuAF had the money to acquire new aircraft.

The Su-57 is not more delayed than the F-35 if you consider when it entered development. I think it will have a technology sophistication in between the F-22 and F-35.

That's not the point the point is they skipped the number sequence from the last offering the SU39 and jumped ahead past 41,43 & 45 to 47 then when that went bust they skipped 49, 51, 53, 55 and went right to 57. Same for the 22+35. It's a marketing gimic.
They rationalized that there top of the line game changer of the 4th gen was SU27 and the ultimate form of it was supposed to be Su37. So any supposed advancement is numbers Su #7
